What is alpha?(Was not much clear in the video)

When function np.hist() was called a parameter alpha=0.8 was sent?And sir said something like obsesity constant(I m not sure as it was not too clear).Can you please tell what it was and what is its meaning?

Hey @nikhil_sarda, mentor said it is opacity constant, like in layman terms it is related to transparency.

Hope this resolved your doubt.
Plz mark it as resolved in my doubts section. :blush:
